CHARLES MOLITOR, OF CHICAGO, ILLINOIS, ASSIGNOR TO ALFRED FRESCHL, OF CHICAGO, ILLINOIS.

COIN-CONTROLLED PUNCHING-BAG APPARATUS.

SPECIFICATION forming part of Letters Patent No. 779,232, dated January 3, 1905.

Application filed June 13,1902. Serial No. 111,492.

To all whom it may concern:

Be it known that I, CHARLEs MoLIToR, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Coin-Controlled Punching-Bag Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a novel construction in a coin-controlled exercising-machine having a cushioned plunger adapted to be actuated by striking same with the fist, the object being to provide an efficient device of this character which Will return the coin to the operator if the latter can succeed in reciprocating the plunger agiven number of times within a specified time limit; and it consists in the features of construction and combinations of parts hereinafter fully described and claimed.

In the accompanying drawings, illustrating my invention, Figure 1 is a front elevation of a machine constructed in accordance with my invention. Fig. 2 is a sectional view on the line 2 2 of Fig. 1, showing the mechanism in side elevation. Fig. 3 is a side elevation of the mechanism looking from the opposite side, the casing being removed. Fig. 4 is a front elevation of the mechanism, the plunger only being shown in section. Figs. 5 and 6 are detail sections, on an enlarged scale, on the line 5 5 of Fig. 3 and show the coin-receiving devices, Fig. 6 showing the parts in the position in which the coin is released and also the plunger. Fig. 7 is a detail section on the line 7 7 of Fig. 3, illustrating the devices for preventing the release of the plunger without releasing the coin. Fig. 8 is a section on the line 8 8 of Fig. 5, showing the coin-return device. Fig. 9 is a section on the line 9 9 of Fig. 3. Fig. 10 1s a view similar to Fig. 9, showing the same parts in different positions.

Fig. 11 is a detail sectional view on the line 11 11 of Fig. 3. Fig. 12 is a view similar to Fig. 11, showing the parts in difierent positions; Figs. 13 and 1 1 are detail sections on the lines 13 13 of Fig. 11 and 14 14: of Fig. 12, respectively.

Referring now to the said drawings, 1 indicates a frame, of cast-iron or other suitable material, which is secured to the rear wall 3 of the casing 2 and carries a sleeve-bearing 1, in which a plunger 5 is longitudinally movable, said plunger 5 being normally held at the outer limit of its movement by means of a spring 6 interposed between the inner end of the plunger and a part of said frame 1. The said plunger 5 is locked at the outer limit of its movement by means of a sliding plate 7, movable in guides on the inner end of the arm 8, carrying said sleeve-bearing at. (Said plate being shown in detail in Figs. 13 and 1 1.) Said plate 7 carries a lug 9, which is engaged by the bifurcated end of an arm 10, carried by a sleeve 11, journaled on a stud 12, extending parallel with said plunger 5 and rigidly mountedin the frame 1. Said arm 10 extends above and below said sleeve 11 and at its upper end is engaged by a spring 18, which serves to normally hold said sleeve in a position to retain said plate in the path of said plunger 5. Pivotally mounted on said arm 8, adjacent the outermost guide for said plate 7, is a bellcrank lever 1 1, one arm of which is provided with a projection 15, adapted to move into the path of and engage a lug 16 on said plate 7 to hold the latter out of the path of said plunger 5. Said bell-crank lever 14 is connected adjacent its pivot with a spring 17, adapted to normally hold same in the position in which said projection lies in the path of said projection 16, and is turned against the action of said spring by means of a lever 18, pivotally mounted between its ends on a projection on the casing of a spring-motor 19, mounted on said frame 1, said lever 18 being turned to throw said projection 15 out of the path of the projection 16 by means of a cam 20 on the main shaft 21 of said motor 19, which engages the upper end of said lever 18. Said shaft 21 of said motor 19 carries a crank 22, which is connected to one end of a tension-spring 28, which serves to actuate said motor, the said spring being brought to a tension by turning said shaft 21 in one direction. Said shaft 21 carries the usual ratchet-wheel 24, engaging a pawl on the spur gear-wheel 25 of the motor, the latter being geared to a governor 26, which regulates the speed of the drive-shaft when actuated by the said spring 23. The said shaft 21 carries three arms 27, 28, and 29 at its forward end, said arm 27 having a pin 30 entering the ogee-curved slot 31 in a lever 32, the arm 28 being provided with a projection 33, adapted to engage an arm 34 on a shaft 35, and a lever 36, pivotally mounted on a stud 37 on the frame 1, and the arm 29 beingpivotally connected with one end of a link 38, controlling a dog 39, hereinafter more fully described. The said lever 32 is pivotally secured at one end to the outer end of a crank 40 on a shaft 41, which is journaled in said frame 1 at its rear end and in a plate 42, carried by the forward end of the sleevebearing 4, at its other end. At its forward end in front of said plate 42 said shaft carries a crank-arm 43, which is adapted to be engaged by the coin 44, held in the bifurcated end portion of an arm 45, loosely mounted on a crank-shaft 46, journaled in said plate 42 and in a bracket 47 mounted thereon, said shaft being turned by means of a crank 48 on the outside of the casing 2. A earn 46 is secured to shaft 46 and serves to engage the inner surface of the arm when the crank is turned so as to throw over the arm 45 from the position shown in Fig. 5 to the position shown in Fig. 7. The said arm 45 is curved and, as stated, is bifurcated at its free end to receive said arm 43, one end being attached to a spiral spring 45, the said free end being provided with flanges 48 to engage the coin and hold the same in a position to engage said arm 43 when said shaft 46 is turned. The latter is located to the right of and below the shaft 41, so that as said shaft 46 is turned the coin will be caused to slide upon said arm 43 and toward the free end of same while turning the latter. \Vhen the coin has passed over the free end of the arm 43, the latter is released and the shaft 41 returned to its normal position by means of a spring 49 engaging same. the normal position of said shaft being determined by a projection 50 on the plate 42, which engages an arm 51 on said shaft 41. The coin after being thus released drops into a hopper 52. As said shaft 41 is turned said lever 32 is moved forward and engages the pin 30 of the arm 27, thereby turning the shaft 21 against the action of said spring 23, thereby throwing said cam 20 out of engagement with the lever 18 and releasing the bell-crank lever 14, which turns into the position shown in Fig. 14. As said shaft 41 is released the lever 32 is carried back to the position shown in Fig. 9, but by the curvature of its slot 31 is guided in a downward direction, so thata projection 53 thereon will strike the arm 54 on said sleeve 11, thereby turning the latter against the action of the spring 13 and throwing said plate 7 to the rearward limit of its movement, where it is held by said bell-crank lever 14, as will be obvious. At the same time that said shaft 21 is turned the shaft 35 is also turned to the position shown in Fig. 10 by engagement of the arm 34 by the projection 33 on the arm 28 of shaft 21. WVhen thus turned, a pin 53 on the lever 36 enters a recess in a cam 54 on said shaft 35 and holds said shaft in said position. Said shaft 35 carries a plate 55 at its forward end, on which are printed the words Stop and Start, which are brought alternately opposite an opening 56 in the casing as said shaft 35 reaches the respective limits of its movement. When said shaft is in the position shown in Fig. 10, the WOIC Start appears at said opening 56. The third arm 29 of said shaft 21 is connected, by means of the link 38, with the dog 39, engaging a ratchet-wheel 57, suitably journaled in the frame 1 and receiving its motion in one direction from said plunger 5. The said dog 39 is normally held in engagement with said ratchet-wheel 57 by the spring 58 engaging the arm 59 thereof, said arm 59 carrying a pin 60, entering the longitudinal slot 61 in said link 38. When said shaft 21 is in the position shown in Fig. 10, the dog 39 is released and thrown into engagement with the ratchetwheel 57 and is free to be moved by the teeth of the latter, andwhen said shaft 21 resumes the position shown in Fig. 9 said dog is held out of engagement with said ratchet-wheel, thus permitting the latter to revolve in a reverse direction. The said ratchet-wheel 57 is connected with a spiral spring 62, by means of which it is returned to its normal position. A bell-crank lever 63 is pivotally mounted on a pin 64 above the said ratchet-wheel and normally held by the flat spring 65 in a position so that one arm thereof projects into the path of a pin 66 on the felly of the ratchet-wheel. The said spring 65 is provided with a pin 67 at its free end adapted to enter either of the two recesses 68 in the upper end of said bellcrank lever 63, and thereby hold the latter in either one of two positions. The operation of this lever and ratchet-wheel mechanism is as follows: As the plunger is reciprocated the link 70 is operated so as to, through the medium of the pawl 73, impart a step-by-step movement, and if the plunger is operated a sufficient number of times the ratchet-wheel makes a complete revolution and said pin 66 will obviously throw the arm normally engaged thereby up out of its path, thereby causing the pin 67 to enter the other recess, 68, and hold said bell-crank lever 63 in a position so that its other arm lies in the path of said pin 66. As said ratchet-wheel is released and reversed by the spring 62 the said pin 66 will throw said bell-crank lever 63 back to its origidog being thus held in a position so that it nal position, so that said pin will again strike the first arm and stop said wheel. As before stated, said ratchet-wheel 57 receives its motion from said plunger 5, which is accomplished in the following manner: Pivotally mounted on said frame 1, above said plunger 5, is a bell-crank lever 69, connected by a link 71 with a collar on said plunger, and by a link with a swinging arm 72, pivotally secured to said frame 1 at the upper end of the latter. Mounted on said link 7 O is a dog 73, actuated by a spring 74 to hold said dog normally in engagement with a pin 75 on said link 70, said will engage one tooth of said wheel 57 at every downward movement of said link 70. On said link 70, at one side, is an L-shaped projection 76, in which is mounted a set-screw 77, which limits the rearward movement of said dog 73, so that when said link 70 reaches the lower limit of its movement said dog 73 will be prevented from moving sufliciently far back to permit another tooth of said wheel 57 to pass. As a further precaution against the possible revolution of the wheel 57 further than one tooth at a time I provide an arm 78, which is pivotally mounted at one end on the pivot of said bell-crank lever 63 and at its free end is engaged by a spring 79, which holds said arm normally in engagement with a stop on said link 70, said spring 79 being connected at its lower end with said link 70. The said arm 78 carries a projection 81, which by the downward movement of the link 7 O is caused to bear upon the wheel 57 and act as a brake in an obvious manner.

On the front of the casing is adial 82, provided with numerals corresponding with the number of teeth on the wheel 57, and on the shaft of the latter is a hand which indicates on said dial the number of times that the plunger is reciprocated.

The coin is droppedinto a slot in the casing and passes through a chute 83 into thearm 45, said chute 83 being provided with an opening 84 between its ends, through which a hook 85, pivotally mounted on the plate 42 and actuated from the shaft 35, projects when the latter is held in the position shown in Fig. 10, thereby preventing a second coin from dropping until the first coin is released and the motor 19 has run down and again locked the plunger 5.

As before stated, the coin when released drops into the hopper 52, whence it passes into a chute 86, the lower end of which is curved and is adapted to deliver the coin into a cup 87 on the outside of the casing. complished by the pin 66 striking and raising the arm of the lever 63, whereby the rod 93 is pulled upwardly, so as to correspondingly operate the lever 88, whereupon the coin falls from the end thereof which projects into a slot 89 in the lower end of said chute 86 and is adapted to support the coin therein. In

This is acthe side of said chute, just above said supported coin, is a slot 90, through which a second coin passes into the receptacle 91, so that only one coin can remain supported on said lever 88. The latter is pivoted between its ends on an arm 92, secured to said plate 42, and atits other end is connected by a link 93 with the bell-crank lever 63, so that when the latter is actuated by the complete revolution of the wheel 57 said lever will be turned out of the path of the coin and the latter will pass into said cup 87. The next coin dropped in will then remain supported on said lever 88. The coin having been dropped in and the lever 48 turned as before described, the plunger is released and by punching the pad 94 on the forward end of same is reciprocated. Meanwhile the shaft 21 is actuated by the spring 23 and'revolves, thereby revolving the three arms 27, 28, and 29. The arm 27 raises the lever 32 until the projection 53 thereon has moved out of the path of the arm 54 on the sleeve 11, thereby leaving the latter free to return to the position shown in full lines in Fig. 9. jection 33 revolves until it strikes and raises the end of the lever 36, thereby releasing the shaft 35, and simultaneously the arm 29-draws down the link 38 until the dog 39 is out of the path of the ratchet-wheel 57. Simultaneously with the release of the shaft 35 the cam 20 will have turned the lever 18 so that the bell-crank lever 14 has released the plate 7, which then is returned into position to lock the plunger 5 against further movement. The said hook is pivotally mounted on said plate 42 and is provided on its rear edge with a projection 95, which is adapted to be engaged by a cam or eccentric 95 on the shaft 35, and thereby held in the position shown in Fig. 6, when said shaft 35 is held in the position shown in Fig. 10. The movement of said shaft 35 also is limited by the projections 96 and 97 thereon, which engage a pin 98 on theplate 42. The arm 45 also carries asegmental rack 99 concentric with the pivot thereof, which is adapted to be engaged by the pawl 100, pivotally mounted on the plate 42 and which is engaged by the flat spring 101 to hold said pawl in one of two positions, said positions being determined by two corrugations 102 and 103 in said spring 101. Said rack 99 is provided with projections 104 and 105 at its ends, the former of which is long, so that it cannot pass said pawl 100, while the other thereof is short and turns said pawl out of its path and into engagement with the corrugation 103 of said spring 101, which holds said pawl in such position until the projection 104 again strikes it and throws it into engagement with the corrugation 102. The said rack prevents the lever 43 from returning to its normal position after being partially revolved, but compels such lever to be turned until'the coin is released.

Should the operator desire to further test The prohis striking powers, I have provided a second spring 106, which is connected at one end with the collar on the plunger 5 and at its other end with the free end of a lever 107, pivotally mounted on a downwardly-extending projection 108 on the forward end of the bearing 1. Journaled in said projection is a crank-shaft 109, provided at its inner end with an arm 110, which when said shaft is turned is adapted to project into the path of said lever 107, as shown in Fig. 4, and hold same rigid, so that at every inward movement of said plunger 5 said spring 106 is expanded. IVhen said lever is free, the same will obviously swing freely in accordance with the movements of the plunger. Said shaft 109 is operated by the crank 111 on the outside of the casing.

In operation after the coin has been inserted into the chute and rests on the end of the lever 88, projecting thereinto, and the means heretofore described for locking the plunger has been released the operator attempts to operate said plunger a predetermined number of times (in the present instance sixty) within a period of time controlled by the motor heretofore referred to. If this be accomplished, the pin 66 of the ratchet-wheel releases the bell-crank lever 63, which operates the lever 88 through the medium of the rod 93 and releases the coin to the operator. If, however, he fails, the spring will return the wheel to its normal position and the coin will pass to the box on the interior of the casii'ig.

I claim as my invention 1. In a machine of the kind specified, the combination with a plunger, devices for looking same against movement, and a motor controlling said locking devices, of coin-controlled devices actuating said locking devices to release the plunger and actuating said motor to relock said plunger within a predetermined time limit, and means whereby if said plunger is reciprocated a given number of times during the time limit the coin will be dropped outside the machine.

whereby said ratchet-wheel is released and returned by the spring to its initial position.

3. In a machine of the kind specified, the combination with a plunger, a coin-receiving chute, a coin-return chute, and coin-controlled devices interposed between said chutes and controlling said plunger to lock and release the same, of devices projecting into said coin-return chute adapted to retain a coin therein, and connection between said lastnamed devices and devices actuated by said plunger to release said coin when said plunger is reciprocated a given number of times.

4;. In a strike-tester, the combination, with striking mechanism, of locking mechanism for holding the striking mechanism normally locked, a time-train controlling said locking mechanism, means for simultaneously releasing the locking mechanism and starting the time-train, said time-train being constructed and arranged to cause the locking mechanism to'lock the striking mechanism after a predetermined period of time, and means for registering the number of blows struck on the striking mechanism during said period of time, substantially as described.

5. In a strike-tester, the combination with the yielding striking-bar provided with the resistance of a locking mechanism for holding said bar normally looked, a time-train controlling said locking mechanism, means for simultaneously releasing the locking mechanism and starting the time-train, said timetrain operating the locking mechanism to relock the striking-bar after a predetermined period of time, and means for registering the number of blows struck during said period of time, substantially as described.
